[Architecture Pattern] Factory Builder 目的 同时提供延迟注入对象.挂载注入项目这两个功能 情景 在开发系统时,如果需要在运行时间才生成并注入对象,可以套用Factory模式来提供延迟注入对象功能.例如:一个监控系统在火警发生时,建立功能对象来启动相关设备(洒水设备.警报设备.警消通报). 物件图 但在实作过程中,延迟注入对象这个功能,常常需要伴随挂载注入项目功能,用以增加系统的延展性,这时可以接着套用Builder模式,来提供挂载注入项目功能.例如:一个监…

[Architecture Pattern] Singleton Locator 目的 组件自己提供Service Locator模式,用来降低组件的耦合度. 情景 在开发系统时,底层的Infrastructure Context.或是核心的Domain Context这些共享对象生成之后,会在系统的许多地方被使用.为了减少共享对象初始生成.参考传递所造成的困扰,可以在系统内套用Service Locator模式,提供统一的静态参考点来生成.存取这些共享对象. Service Locator参考…

[Architecture Pattern] Repository实作查询功能 范例下载 范例程序代码:点此下载 问题情景 在系统的BLL与DAL之间,加入Repository Pattern的设计,能够切割BLL与DAL之间的相依性,并且提供系统抽换DAL的能力.但在软件开发的过程中,套用Repository Pattern最容易遇到的问题就是,如何在Repository中实作「查询」这个功能.像是在下列这个查询订单的页面,系统必须要依照用户输入的查询条件,来从DAL中查询出所有符合条件内容的…

软件架构模式 缺少规范架构的程序通常会变得紧耦合.脆弱.难以更改,缺少清晰的发展方向和愿景.这本小书用50多页介绍了常用的5种常见架构模式,相信不管是大牛还是萌新都会有所收获,特别是对我这种偏爱系统设计.架构.模式的人.当然,此书也只是高层的讨论,能够起到归纳总结.理顺思路的作用.如果想实际应用,还是需要从代码入手,站在架构模式的角度分析优秀的项目源码. 分层架构(Layered/N-tier Architecture) 分层架构的组件按垂直模式组织成多层,每一层表现为程序的一种角色.分层架构大…

为什么游戏公司的server不愿意微服务化? - 知乎 https://www.zhihu.com/question/359630395 我大概说了,方便测试,方便维护,方便升级,服务之间松耦合,可多语言开发,自动扩容-之类的点 然后他说游戏server不太需要微服务,因为要求real time,做微服务会影响效能,分模组来开发就好 作者:陈宏基链接:https://www.zhihu.com/question/359630395/answer/954452799来源:知乎著作权归作者所有.商业…

微内核架构(Microkernel Architecture) 微内核架构有时也被成为插件架构模式(plug-in architecture pattern),通常用于实现基于产品的应用,如Eclipse和Firefox.然而许多公司也将内部的业务软件做成软件产品,提供版本.发版说明和插件特性.微内核架构模式通过插件向核心应用添加额外的功能,提供了可扩展性和功能的独立和分离. 模式描述 微内核架构包含两部分组件:核心系统(core system)和插件模块(plug-in modules).应用…

[引言]最近在Youtub上面看到一个讲解.net设计模式的视频,其中作者的一个理解让我印象很深刻:所谓的设计模式其实就是运用面向对象编程的思想来解决平时代码中的紧耦合,低扩展的问题.另外一点比较有见解的是,区分了设计模式(Design Pattern),结构模式(Architecture Pattern),架构类型(Architecture Style). 如下图所示 Design Pattern:是基于代码层面的,就是针对解决功能模块之间的问题而采用恰当的设计模式,比如依赖注入,简单工厂,适…
